Quick Question
 

Im about to purchase the H&S Max Flow Manifold with the Boost tube, I have the Egr unplugged but do i have to buy an EGR and Cooler Delete to run this or Just a Cooler delete. Im kind of confused:humm:

You will need to remove (Delete) the EGR all together with the aftermarket intake horns.

So that means the aftermarket intake horn takes care of that...the cross over tube is part of the cooler..correct?

Yes that's correct
